SOLIDWORKS Simulation SOLIDWORKS® Simulation Standard, SOLIDWORKS Simulation Professional, and SOLIDWORKS Simulation Premium are separately purchased products that you can use with SOLIDWORKS Standard, SOLIDWORKS Professional, SOLIDWORKS Premium, and SOLIDWORKS Ultimate. Contents Automatic Detection of Underconstrained Bodies You can detect rigid body modes at the early stage of a linear static study's solution. Bonding Interactions with Offset The enforcement of node-to-surface bonding interactions between geometries within a user-defined gap is improved. Contact Penalty Stiffness for Shells A new algorithm is introduced to apply penalty stiffness for contact interactions of shells. This enhancement improves performance and accuracy for a large range of shell thickness ratios. Contact Penalty Stiffness Control for Nonlinear Studies You can adjust a scale factor for the penalty stiffness applied to surface-to-surface contact interactions when solving nonlinear studies. Edge Weld Connector Several enhancements for the Edge Weld connector improve its usability. Enhanced Pin Connector The introduction of a distributed coupling algorithm enhances the performance of studies that use pin connectors. Exclude Bodies from Analysis You can exclude multiple bodies from an analysis. General Spring Connector You can specify a general spring connector between flat, nonflat, and concentric cylindrical surfaces. Geometry Correction for Surface-to-Surface Bonding Simulation accuracy is improved for studies with bonded curved surfaces (surface-to-surface bonding formulation) when the mesh sizes of the source and target surfaces differ. Mesh The total meshing time by the Blended curvature-based mesher is reduced for assemblies that have multiple identical parts.
